Runtime Performance

SSR Performance

Measured on GitHub Actions (ubuntu-latest, Node 24) using custom SSR benchmark apps.

Framework Ops/sec Avg Latency Body Size Duplication
Baseline HTML 706 1.417ms 96.81kb 1x
Next.js 129 7.74ms 198.59kb 2x

Methodology

  • Each framework renders a table of 1000 rows with two UUID columns
  • Mock HTTP requests bypass TCP overhead for accurate rendering measurement
  • Data is loaded asynchronously to simulate real-world data fetching
  • Duplication factor indicates how many times each UUID appears in the response (1x = optimal, 2x = includes hydration payload)
  • Benchmarks run for 10 seconds using tinybench
  • Astro, Nuxt, and SvelteKit handle Node.js HTTP requests natively. React Router, SolidStart, and TanStack Start use Web APIs internally, so benchmarks include the cost of their Node.js adapter layers (@react-router/node, h3, and srvx respectively)
  • Next.js defaults to React Server Components (RSC), a different rendering model than traditional SSR. To keep the comparison fair, Next.js uses "use client" to opt out of RSC and use traditional SSR + hydration like most of the other frameworks
